This thing s ridiculous but in the best way. I love the color change. Blue is cold. Green is nuke warm. Red is hot... And blinking red is scalding.Colors do dim with pressure change. So if you want a real rain drop effect in the rain head the colors will be muted.4 stars because you can heat the fans spinning to generate the lights. But isn't so. Bad when you are in the water.First of all I have to say that I did have a leaky valve. Got a hold of both the seller and Amazon. It was taken care of immediately. Seller was more than helpful which was very pleasing. With that being said I loved everything about this product. I did a lot of research on these shower heads and this one was very pleasing to me. I love that it changes colors. The plumber had no problem installing it.Installed this shower and valve about 8 months ago. Was easy to install and worked great. Now the LED color only works on Red and the valve is leaking randomly (flowing water to shower head when valve is off). A shower head and valve should last longer than a few months.It was pretty good if I’m being honest. You gotta make sure that you have a lot of water pressure though. One problem I had is that the led lights never lit up.The materials used appeared top notch unfortunately it was too large for our standard shower stall. It’s big!This is a great shower head. But, on mine, the lights went out after about a year.I love it. I have no complaint abt this product at all. Water fall feeling and relaxing. The pressure of water very nice. Highly recommended. It’s like my own personal sauna in shower.I love the product it was grat size I used the product in my shower. The lights are bright
